CONTROL INPUT DI1 (RESET)
Configurable as direct or inverse switch or push button!
Contact input
Connection of potential-free contact that is suitable for switching
‘dry’ circuits.
Switched voltage: 5 V
Switched current: 1 mA
Optocoupler input
Actively switched optocoupler input
Nominal voltage: 24 V DC external
Logic ”0”: -3 V…+5 V
Logic ”1”: 15 V…30 V
Current demand: max. 6 mA
OUTPUTS
RELAY OUTPUTS LC, OUT2
Type: 2 NO contacts with a common terminal
Max. contact rating: 500 VA, 250 VAC, 2A at 48...62 Hz,
resistive load
Min. contact rating: 6V, 1 mA DC
Switching cycles
(electrical):
for I=1A/2A: ? 800.000/500.000 (at
250VAC, resistive load)
Note:
If the relays LC and OUT2 operate external contactors, these must
be fitted with RC snubber circuits to manufacturer specifications
to prevent excessive voltage peaks at switch-off.
OUT3 AS UNIVERSAL OUTPUT (OPTION)
Galvanically isolated from the inputs. Parallel current/voltage
output with common ‘minus’ terminal (combined use only in
galvanically isolated circuits).
Freely scalable
Resolution: 14 bits
